ROLLER-SKATE.

Specification-of Letters Patent.

Patented Jan. 6, 1920.

Application filed March 8, 1919. Serial No. 281,328.

To all whom it may concern:

Be it known that I, FREDERICK GUNNAR- 'soN, a citizen of Sweden, residing at Ogden, in the county of Weber and State of Utah, have invented new and useful Improvements in Roller-Skates, of which the following is a specification.

This invention relates to roller skates, particularly to those of the so called bicycle that is those having only two wheels, has for its object the provision of a skate in which the wheel bearings are supported beneath the foot engaging plates by means of springs, the resilience ofwhich will take up the shocks and jars incident to the travel of the skate over a surface, and whereby the maximum degree of comfort will be afforded the user. i 4

An important object is the provision of a skate of this character which will be simple and inexpensive in manufacture, simple and durable in use, and a general-improvement in the art.

lVith the above and other objects and 'advantages in view, the invention consists in the details of construction to be hereinaftermore fully described and trated in the accompanying drawing, in which- Figure 1 is a bottom plan view of a skate ..1 constructed in accordance with my invenftiOIl,

Fig. 2 is a side elevation thereof, and Fig. 3 is a cross sectional view taken through one of the wheels.

Referring more particularly to the drawing, the numerals 5 and 6 designate plates connected by means of the usual bolts 7 extending through elongated slots 8 whereby the length of the skate may beadjusted, the plate 5 having one end enlarged to form aheel engaging portion 9 and the plate 6 having one end enlarged to form a sole engaging portion 10. A suitable upstanding yoke 11 is secured to the heel portion 9 and is provided with suitable straps, not shown, of ordinary construction and arrangement whereby the skate may be partially secured upon the users foot. The sole engaging portion 10-" is provided with theusual sole engaging "clamps 1?. adjustable by means of the usual form of screw 18. The above described parts are well known in the art and no novelty is claimed for them.

In carryin out my invention I provide upon the un er side of the sole engaging claimed, and illus- .7 irregularities.

skates will be very\ portion 10 of the plate a pair of oppositely bowed substantially V-shaped springs 14 which may be riveted or otherwise suitably secured upon the sole engaging portion 10 and which carry at their free ends bearings 15 arranged in spaced parallel relation.

front wheel 16 is provided which has its axle 17 journaled in the bearings 15. A U-- shaped yoke 18 also receives the axle 17 and is disposed horizontally, that is at right an: gles to the springs 14. The bight portion of the yoke 18 has secured thereto, as shown at 19, one end of a resilient strip 20, which extends at an angle toward and which has its other end secured to the under side of the plate 6, as shown at'21.

The structure at the rear wheel is. identically the same as the structure at the front wheel except that the resilient strip 22, corresponding to the strip 20 of the front wheel structure, extends in the opposite direction and the yoke 23, corresponding to the yoke 18, is also oppositely disposed.

From the foregoing description and a study of the drawings, it

upon the springs 1 1 at the front and rear" wheels will take up any shocks and jars incident to the passage of the wheels over any The springs 14 in such case permit the wheels to move toward or away from the supporting plates of the skate, as will be obvious and it is apparent that the provision of the resilient-strips E20 and 22 serves to afford suflicient rigidity to the wheel supporting structures while permitting the proper flexibility. It will be evident that as a consequence the use of the desirable inasmuch as they will afford comfort to the user. 7

While I have shown and described the preferred embodiment of my invention, is of course to be understood that I reserve the right to make such changes in the form, construction, and arrangement of parts as will not depart from the spirit of the invention or t e scope of the subjoined claim.

Having thus described my invention, I claim A skate comprising a foot engaging memher, a pair of oppositely bowed substantially V-shaped leaf-springs secured transversely .95 I e maximum degree of vertically downwardly/and being formed. as. the yoke at the rear Wheel entending forill bearing members, a wheel disposed between Waruly and an inclined resilient strip seeach pair of springs and having its axle jourcured at one end to the bight of each yoke nally received within said bearings, a h0riand having its other end secured to said zontall disposed U-shaped yoke straddling foot engaging member, said resilient strips each w eel and having its arms disposed inconverging upwardly. 5 Wardly of said bearing members and jour- In testimony whereof I afiix my signature. nally engaging said axle, the yoke at the forward Wheel extending rearwardly and FREDERICK GUNNARSON.
